At the lake

You can enjoy swimming in the lake. There are also plenty of camping sites available like Jokohama with a great view of the setting sun; Shidahama, Tenjinhama in the pine forest with a long and wide shallow sandy beach; and the Tenjinhama sandbank at the estuary of the Nagase-gawa River. Also worth mentioning are Kanizawahama and Nagahama, where the waves are calm enough to allow for easy swimming.
